The model LL-SG2-*/* transponder is available as part of the LIFELINE status-monitoring system.
The LL-SG2-*/* transponder continuously monitors node parameters, executes commands, and
reports to the polling computer when interrogated. Section 2, "Overview," provides additional
information regarding status-monitoring functions.
Detailed instructions for installing the LL-SG2-*/* transponder are provided in the Transponder for
SG-2000 LL-SG2-*/* Installation Sheet, packaged with the transponder. Following physical
installation, the transponder must be added to the software system and the alarm parameters must be
configured. To complete these tasks, refer to the LIFELINE for Windows Software Operations
Manual.
